Guangzhou Steel Structure Terminology

Steel structure is very common in our country, but many people say professional terms, most do not understand, the following Guangzhou steel structure manufacturers - Shengbang steel structure for everyone to analyze the next.

1, strength: component cross-section material or connection resistance to damage ability. The strength calculation is a calculation that prevents the structural member or connection from breaking due to the strength of the material being exceeded.
2, carrying capacity: the structure or components will not be due to strength, stability or fatigue and other factors can withstand the maximum internal force; or plastic analysis of the formation of the largest internal force when the destruction of institutions; or to adapt to continue to carry the deformation of the internal force.
3, brittle fracture: generally refers to the steel structure in the tensile stress state without warning plastic deformation and the sudden occurrence of brittle fracture.
4, the strength of the standard value: the national standard of steel yield point (yield strength) or tensile strength.
5, the strength of the design value: the value of steel or the connection of the standard value divided by the corresponding resistance after the sub-coefficient of the value.
6, First-order elasticity analysis: Regardless of the influence of the second-order deformation on the internal force, the equilibrium condition is established according to the undeformed structure, and the internal force and displacement of the structure are analyzed according to the elastic stage.
7, second-order elasticity analysis: Considering the influence of the second-order deformation on the internal force, the equilibrium condition is established according to the structure after displacement, and the internal force and displacement of the structure are analyzed according to the elastic phase.
8, buckling: bar or plate in the axial pressure, bending moment, shear force alone or together under the joint force suddenly occurred with the original state of the larger deformation and loss of stability.
9, web flexion strength: web flexion can still continue to bear the ability to bear the load.
10, the general high and low ratio: the parameter, the value is equal to the steel bending, shear or compression yield strength divided by the corresponding web bending, shear or local pressure elastic buckling stress of the square root.
11, the overall stability: under the action of external load, the entire structure or components can be buckling or instability assessment.
12, the effective width: in the cross-section strength and stability of the calculation of the width. Assuming that the board is valid
13, effective width coefficient: plate effective width and the actual width of the plate ratio.
14, Calculate the length: the geometric length of the component between its effective constraint points multiplied by the equivalent length of the rod end deformation and the load condition to calculate the aspect ratio of the component. The length of the weld used to calculate the weld connection strength.
15, slenderness ratio: component calculated length and component cross section radius of rotation ratio.
16, conversion slender ratio: in the axial stability of the components of the overall stability calculation, according to the principle of equal force, the lattice component converted to real abutment components for the calculation of the corresponding slenderness ratio or bending and twist Torsional instability is the slenderness ratio used for bending instability.
17, support force: In order to reduce the lateral support provided by the free length of the compression member (or the compression flange of the member), in the direction of buckling of the support member (or member compression flange), The lateral force of the member (or the component is pressed).
18, no support pure frame: rely on components and nodes connected to the bending ability, resistance to lateral load frame.
19, strong support frame: in the support frame, the support structure (support truss, shear wall, elevator shaft, etc.) lateral lateral stiffness, the frame can be regarded as no side of the frame.
20, weak support frame: in the support frame, the support structure anti-lateral stiffness is weak, the framework can not be regarded as no side of the frame.
21, swing column: the frame at both ends of the hinge can not resist the lateral load of the column.
22, the column web node domain: the frame beam column of the rigid node, the column web in the beam height range of the region.
23, spherical steel bearings: the structure at the bearing can be rotated in any direction of the steel sphere as the force of the hinge bearing or removable bearing.
24, rubber bearings: to meet the requirements of the bearing displacement of rubber and thin steel plate and other composite products as a bearing support force of the bearing.
25, in charge: steel pipe structural components, in the node at the continuous through the pipe, such as truss in the chord.
A pipe in a pipe structure that is disconnected at the node and connected to the main pipe, such as a web bar connected to the main pipe in a truss.
27, the gap node: the two branches of the toe to leave a certain distance from the tube node.
28, lap node: in the steel pipe node, the two branches of the node overlap with each other.
29, the plane tube node: branch pipe with the supervisor in the same plane connected to each other nodes.
30, the space tube node: in different planes within the branch pipe and the pipe connected to the formation of the pipe node.
31, composite components: by more than one steel (or steel) connected to each other components, such as the shape of the cross-section or box-shaped composite beam or column.
32, steel and concrete composite beams: by the concrete wing and steel beams through the combination of shear joints can be the overall force of the beam.
